Aplicação de teste de usabilidade e avaliação heurística em aparelho medidor de pressão digital de pulso

Nowadays, medical equipment available are intended to be safe, practical and efficient, and industries innovation sectors invest in new technologies in order to attract more customers through the delivery of quality and reliability. However, some details are only visible to the user's eyes. Human Factors Engineering pursuits the systems adaptation to humans needs and limitations, considering their cognition to products and systems design. In this context, this study applies Usability Tests combined with Heuristic Analysis to a Wrist Digital Blood Pressure Meter in order to validate its safety and feasibility, and also to propose improvements to the product and its instructions manual, emphasizing the importance of users understanding regarding the product’s use. As a result, the product violates some usability heuristics, such as feedback, error message, error prevention and help and documentation, as well as it presents some obstacles in the execution of certain user tasks, in which this research suggests improvements.
